Exposure Principals Assignment

Shutter Speed: 

Shutter speed is the amount of time the shutter screen stays open or the duration for which the light hits the mirror. Using the correct shutter speeds can make people or objects frozen in time or it can show the trail capture. I experimented with taking sports pictures to practice using fast shutter speeds. For the photo showcased below, I set the camera to manual mode and set the shutter speed at 1/1000 of a second. Setting it at that 1/1000th of a second, allowed me to take this photo with out motion blur. 

Aperture:

Aperture is the width of our opening for our lens. Adjusting this setting in your camera allows you to control the area of focusing your picture. Depending on your camera settings, you can make the background blurry or in focus. In photography, aperture is expressed in "f-stops" (For example f/1.4, f/2.8) They are a way of describing how open or closed the aperture (lens light hole) is. A smaller f-stop means a larger aperture, while a larger f-stop means a smaller aperture. Smaller aperture settings, will expand the area of sharp focus, but give you a semi blurred background. On the other hand, if you have a larger aperture setting , you will have a reduced area of sharp focus. you will have parts of a subject in focus wit a blurry background. For the photo below I used a shutter speed of 1/250th of a second, aperture setting of F4.0 and an ISO setting of 100. Having the aperture set at F4.0 allowed me to have my subject in focus, while the background fuzzy.

ISO:

ISO is the measure of the camera's sensitivity to light. ISO settings can be anywhere from ~100 - 6400 (or higher on pro cameras), and these snubbers have a direct relationship with the camera's sensitivity. A lower ISO setting makes it less sensitive and a high setting makes it more sensitive to light. In bright conditions, using a lower ISO setting would be recommended. Likewise, in dark conditions a higher ISO setting would be preferred.
